Abstract

A vehicle has an ECU (40) for controlling an engine (4) which uses a mixed fuel containing gasoline and alcohol. The ECU (40) includes an engine state detecting unit (46) configured to detect the state of the engine (4) related to an engine temperature, a determining unit (44) configured to determine whether or not the state of the engine (4) is a predetermined state, and a restricting unit (47) configured to restrict starting of the vehicle based on the result of a determination by the determining unit (44).
This enables the engine to start running without putting the engine under excessive load, and without the need for the engine to include a large-sized heating means.
